Second Hand Narrow Strip Hot Rolling

1. Strategic Production Capabilities

This hot rolling steel strip mill delivers 300,000 tons/year of premium narrow-gauge coils (136–430mm width), equally split between cold-rolled feedstock and commercial hot-rolled steel. Engineered for specialized applications, it processes carbon structural steel (GB/T700-2006), low-alloy steel (GB/T1591-2008), and high-grade alloys with unmatched efficiency.
